ok guys ive had this problem for awhile now and cant firgure it out ive tried alot of things
heres the problem
I can drive the car anywhere fine and it drives great when its cold, i turn on the lights and heat and stereo and its great
but once it warms but it starts to get the problem. The car runs and drives fine when no electronics are on when its warm but as soon as i turn on my headlights or heat or stereo the car starts bogging(rich or lean dont know). It just doesnt want to go like hitting the rev limite or something. only happens when its warm and electronics are on. As soon as i turn the elec.s off the car runs good again

ive changed the alt., battery, water collant temp. sensor, tbs, got a new harness for the stereo and dash. checked timing, comp. numbers were solid. changed maf, fuses, underhood fuse box. ripped out the alarm. ripped out the stereo, even went as far as riping out my jdm power mirror which took me months to figure out.

heres some testing ive done.
The car runs great when i take off coolant temp sensor, or o2 sensor, or tps. idles funny but doesnt bog. when i disconnect o2 it runs great.

any ideas, i can paypal or send money if u know what it is and can help me out. its been killing me, right now im driving without o2 sesnor plugged in and dont feel like half assing this as ill be boosting it later on

anything will help at this point
thanks for reading my big paragraph

check your map, once the car gets warm the singals will change. i dont think you mentiod anything about the map, just unplug it and drive it till warm and see if the bogging is still there, if that takes it away then test the sensor ill tell you how if thats the problem

v8killaz

ill check today
im at school right now but i dont remmeber testing it so ill see what happens bro
updates soon

check your IAT and clean the injectors, sounds like you done everything else I would have done already.

Replace the O2 sensor. It's the only sensor that is completely ignored by the ECU until the engine is hot.

v8killaz

is it the only ecu that turns on when how or no
and i dont mean warm i mean when the guage reads 50%
as soon as it hits 50% like 10 seconds later it starts to bog

and i checked the maf and took it off and it ran good but idles weired but tested it it read good

Former User

???

Again, the O2 sensor signal is completely ignored by the ECU until the ECT sensor indicates that the engine is fully warmed up.

v8killaz

it never throws a code though, never did
i meant is the o2 the only sensor that starts to work when engine warms up

Former User

Bad sensors don't always throw a code.

Yes. In addition, you already showed that unplugging the O2 sensor eliminates the problem.
